  1. Chlamydomonas

  2. Funaria

  3. Dryopteris

  4. Riccia

Show answer
Correct Option: C
Explanation:

Gametophytes have sessile jacketed multicellular sex organs. The male is antheridium and female is archegonium. Antheridia form biflagellated (Selaginella, Lycopodium) or multiflagellated (Dryopteris) male gametes. Antheridium producing about 32 anthropoids. Each anthropoid is large antinuclear coiled and multi flagellate.

Zygote do not undergo reduction division immediately but produce multicellular sporophyte in

examples of bryophytes plant kingdom biology

  1. Funaria

  2. Selaginella

  3. Cycas

  4. All of the above

Show answer
Correct Option: A
Explanation:

Zygotes do not undergo reduction division immediately. They produce a multicellular body called a sporophyte. The sporophyte is not free-living but attached to the photosynthetic gametophyte and derives nourishment from it. Some cells of the sporophyte undergo reduction division (meiosis) to produce haploid spores. So, the correct option is "A" (Funaria).
